(Adds discovery of additional body parts)
By Gustavo Palencia
TEGUCIGALPA, July 9 (Reuters) - Honduran police said on Tuesday they believe a severed head and other body parts found in a region of the country ravaged by Mexican drug cartels belong to a popular television journalist kidnapped last month.
Honduran police chief Juan Bonilla said officers found the clothing Anibal Barrow was last seen wearing and a savings account booklet in his name near a partially buried and decomposing headless torso in the northern city of Villanueva.
The evidence suggested the body, which had also had its arms and legs removed, belonged to Barrow, Bonilla said.
Later on Tuesday, police said they had also found the victim's head, arms, legs and feet.
Four people have been arrested in connection with the killing, and police are looking for six other suspects, Bonilla said, adding that no motive for the murder has been established.
Lying about 100 miles (165 km) north of Tegucigalpa, Villanueva is next to San Pedro Sula, Honduras' second-largest city.
Violence linked to organized crime in Honduras has surged in recent years, partly due to the presence of Mexican drug gangs that use the country as a transit point for contraband.
Barrow, 58, a popular morning news anchor on Globo TV, one of Honduras' largest broadcasters, was abducted by armed men on June 24 in downtown San Pedro Sula.
His death would put the number of murdered Honduran journalists since 2010 at 28, according to the country's human rights commission. It would also be the first time a journalist had been decapitated and dismembered in Honduras.
"This horrendous crime intimidates all Honduran journalists. We strongly urge authorities to clarify ... whether or not the motive (for the crime) was his profession," said Juan Mairena, president of the country's journalist association.
Honduras has the highest murder rate in the world, according to the United Nations, with 87 killings per 100,000 in 2012, and San Pedro Sula is the world's most murderous city. (Writing by David Alire Garcia; Editing by Xavier Briand and Mohammad Zargham)
